Since we don't really know the exact nature of this 'naruto x tsume lemon fanfiction' (assuming no adult content), it could be a story that delves into their individual personalities more deeply. Naruto's never - give - up attitude might influence Tsume in some way, or Tsume's tough - as - nails nature could teach Naruto a thing or two. It could also be set in a different time period within the Naruto world, like a prequel - type story showing how their paths could have crossed earlier than in the main story.
Well, if it's a proper fanfiction without any inappropriate elements, it could be about how Naruto and Tsume interact in a story that might deviate from the original Naruto plot. It could be about them teaming up for a mission, or having some deep conversations that show a different side of their friendship or comradeship. Maybe it also involves some cool action scenes where they fight together against a common enemy.
